[research] LLM adopts false facts from irrelevant or adversarial documents in a RAG retrieval set

Implement a strict relevance filtering step \(e.g., NLI classifier or LLM-as-a-judge\) between retrieval and generation, explicitly instructing the model to ignore retrieved documents that contradict each other unless one is authoritative.

Journey Context:
RAG assumes retrieved documents are true and relevant. If the retriever fetches a document containing a common misconception or adversarial text, the LLM will often parrot it, overriding its own correct parametric knowledge. This is the 'distractor' failure mode. You cannot blindly trust the retriever; the generator must have a defense mechanism against poisoned or irrelevant context, even if it means discarding retrieved context.
